es to appara for heating dwelling housesl or other V.st-ruetures in which the luel used is or other to pro-- duce. a simple and efficient. apparatus for that purpose. l accomplish 4this obje-ct by the apparatus described herein and illustrated in the accoinpanying` drawings in Figure 1 is a section on the line l-1 ol?l 3, with a portion of the combustion chainlier and air heating apparatus partly' broken a ay for cleat-ness of illustration. Fig. is an end elevation, with lparts broken Fig'. 3 is a plan, with -a portion ol' the top ol' thiyouler jacket broken away.

In the drawings the outer casino; orjacliet is composed oil a she-et iron body 5 and a sheet iron lcover G which niay be lined with. i asbestos 7 it' desired, the lining being onlitted in the views, exceptI in Fig. 2. The. liningr I can be omitted il' desired, but itis .preferred as it prevents excessive radiation from the outer jaelet. Near the bottom of the body are screened openingsS for the passage into the jacket of thev cold air. At the top are g the conducting lines 9 which carry the, heat-.i ed air to theplace ol'use not shown. Within the outer jacket are batteries 10 ol' air heating llues separz'lted by smaller combustion l, fines 12. These batteries are composed of i the larger, air heat-ingilues 11 which are open at the top and closed at the bottom, and the smaller and narrower combustion ilu-es 12.l which are o] the top.

.ln the drawings l have. shown two bat-,l teries ol' ilues each composed ol' 5 air heating llues and lour smaller coinlnistion ilues, but' l any other number ol' tlues may be used.

)en at the bottom and closed at y end walls and 4thel air heating flues intermediate the end lines have openings 14 in-.the side walls just above tliecoinbustion charnber 15. The combustion fines '12. at the bottom openinto the combustion chamber l l l and are connected by ports 16 near the top with the an' hea-ting tlues so that the hea-ted rr winch passes up the combustion fines a p out through. portsv 16 and joins the ire-ated air which passes up through the other fines. r

117 is a gas or other Vapor burner oi' any approved construct-ionwhich extends longitudinally throughthe combustion chamber 15 near the bottoni thereof.' This burner 4is, preferably provided with ports 1S at each side anda little above the center of the burner as best shown in Figs. 1 and 2. 19 is a combustion' air cylinder which passes through the outer jacket and into the. `en d ol' the combustion chamber 4as best shown in Fig. 1. The outer-end is provided with a screen 2O to screen theair that goes into the combustion chamber. Each battery of tlues is preferably provided with a supporting traine 21,' which is preferably l'orrned oi small pipe and iittings. When the entire heating ol'the dwellingr or .other structure is to be accon'iplished by the use ol' hot air alone the foregoing ctnnprises n'iy improved heating,r apparatus, but it is ,sometimes desirable to provide additional heating means and to that end .l provide. in the combustion' chamber a Water vheater which is composed 0ll pipe 22 which runs from the radiator lin the room to bel heated, no shown, down to the outer casing andinto the saine at the top thence down to and en- -ters the combustion chamber at the, back thereof and then toward-the front vat one side oi' and above the burner thence crossing to the. other side and following the samecourse 'as the. incoming pipe back to the radiator. In the drawings-l have shown only one combustion' chamber equipped with Water heat-- ving appara tus', but all the combustion chan1 bers may be likewise equipped il' desired` By thls construction a combination ol hot air and hot water heating can be' used, as the saine burner will heat-both air and Water at the saine time. By a suitable arrangement ol' pipes, not illustrated because no part. ot' iny invention, the hot air and hot Water can be conveyed to the saine room for lieatingit, or hot Water can be 'carried to one room for heating the same, While hot air is conveyed to another rooinlor heating it. Y

In order to 'prevent the combustion flues troni becoming too highly heated I provide a pluralityol' simal1 openings or ports 23 in the into the air heating ilues..

' and -conducting end wallsy so thatcold air may be drawn thereinto from the air that enters the outer casing. I also provide like ports 24 in the Walls of the combustion chamber near the tcp thereoi` just below ports ZB'for the entry thereinto of cool air. By arranging these combustion and air heating {lues in batteries as shown inthe drawings the air to be heated is divided up into a considerable number oll ascending columns and likewise the products 0l combustion are divided up into a considerable number ol' ascending columns retained Within narrow spaces thereby heating the Walls and causing radiation ol the heat It desired the cold air may be led into the outer casing ol' the furnace by a pipe leading from the outside 0i' the building.

Having described my claim is:

1. A heating apparatuscomposed ol' an outer casing, said casing having air iniets near the bottom thereof; a batteryy ol' conibustion and air heating iiues Within said outer casing terminating below the top of the outer casing, the combustion ilues communicating With the air heating iues near the top thereof, said air heating lues being open at the top'and closed atthe bottom and thel combustion tlues being open at the bottom and closed at the top; acombustiom chamber below said battery ol' iiues in com'- munication with the'cornbustion flues; a vapor burner Within said combustion chamber; i'lues connected to the top of the outer casing, said conducting vliues being adapted to carry the heated air to a place oi' use. i

invention what I 'the bottom and having y day oll August.,

2. A heating apparatusl composed elA an outer casing having air inlets near the bottom thereof; a battery oi combustion and air .heating flues Within said casing, said air heat;

ing lues being open at the top andvclosed at air inlets in the side or end Walls thereof near the bottom and being separated by combustion lines, said combustion lines being narrower tlues than the. air heating tlues, and having ports in ythe side walls thereotl near the top opening into the air heating iiues and other ports in the end f walls near the bottom thereof; a combustion chamber belouv said battery oi lines; and a. vapor burner Within said combustion chamber.

3. A heating apparatus composed oll an outer casing having air inlets near the bottom thereof; a plurality of batteries of flues Within said outer casing, each battery being '-omposed oi a plurali@v of air heating fines closed at the bottoni and open at the top separated 'by narrower combustion Hues, said il ues being in communication with each other near the top; a combustion chamber below each battery olA 'llues in communication with the combustidn'liues; said combustion ilues being open at the bottom and Closed at. the top; a vaporburner extending longitudinally each ol` said combusticn chambers near 1re bottom thereof; and-a `waterheater witiin one or moreoi' said-combustion chambersi` In Witness that i claim the l'oregoin" ,iff have hereunto suliscribed na): nanie this itl th,y
